It's a weird thing. I'm not old, but I feel pretty ancient mind wise, although it is still young and can make slight mistakes. Taking care of responsibilities is what I've gained finally, but I still go to raves n wear baggies and party kiddies under the table :p
My joints have started to crack and I hurt a bit, but I feel young and fresh. Just lose a bit of weight and I'll be looking as fresh as an, um, baby's arse?
